An administrator is replacing 15,000rpm hard drives in a server. Which of the following is the interface type the drives most likely use?
The correct answer is A. SAS. SAS (Serial Attached SCSI) is the enterprise-grade interface designed for high-performance server drives. SAS drives are available at 10,000 RPM and 15,000 RPM spindle speeds and are built for continuous 24/7 operation, high IOPS, and multi-initiator support. SATA (C) is a consum

Explanation
SAS (Serial Attached SCSI) is the enterprise-grade interface designed for high-performance server drives. SAS drives are available at 10,000 RPM and 15,000 RPM spindle speeds and are built for continuous 24/7 operation, high IOPS, and multi-initiator support. SATA (C) is a consumer/prosumer interface - SATA drives typically top out at 7,200 RPM (some reach 10,000 RPM in limited cases) and are not rated for the same duty cycles as SAS. eSATA (B) is an external version of SATA, used for external desktop drives, not high-RPM server drives. IDE (D) is a legacy parallel interface that is obsolete in modern servers and was never used with 15,000 RPM drives.
